EMOM & HIIT Timer Resero

Imarum

About this app

Resero is an EMOM timer that adapts to how you actually train. Build any workout, interval set, or start an exercise routine in seconds. No ads.

RE-SE-RO stands for REps, SEts, and ROunds — the three things every serious workout timer needs to get right.

WHAT MAKES RESERO DIFFERENT

Premade Workout Library
Skip the setup and dive straight into training. Pick from professionally structured routines across Tabata, EMOM, HIIT, and combat sports — or customize any library workout to fit your exact goals.

Fully Customizable
Build every interval, rep, set, and rest period with total precision. Configure an EMOM timer for strength work, a HIIT timer for conditioning, or a round timer with custom lengths and warning bells.

Sub-Timers Inside Every Rep
This is where Resero goes further than any other workout timer. Break a single set into its own timed phases and Resero cues each one: 12 squats at 2 seconds down, 1 second hold, 1 second up. Built for tempo training, time under tension and controlled eccentrics.

Smart Audio Cues
Never miss a transition or drown out your music. Resero automatically dims your background audio during cues, then seamlessly restores the volume.

Runs in the Background
Change your music track or answer a text without interrupting your workout timer or audio cues.

100% Ad-Free
Zero video pop-ups, zero banner clutter, zero mid-circuit interruptions. A gym timer should never try to sell you something mid-set. Free to download.

Automatic History Log
Completed sessions are saved automatically to your in-app calendar. Review any past session and build long-term consistency.

High-Visibility Interface
Massive buttons built for effortless tapping mid-workout and dripping with sweat. Prop your phone on a bench and this gym timer doubles as a gym clock the whole room can read.

BUILT FOR EVERY DISCIPLINE

HIIT & Tabata: Fine-tune high-intensity work-to-rest ratios with a HIIT timer you actually control.

Boxing & MMA: Set custom round lengths, rest periods and warning bells — a proper boxing timer, not a repurposed stopwatch.

Weightlifting & Calisthenics: Time every lift set, set your rep tempo with sub-timers, and recover with exact rest countdowns.

EMOM & Circuit Training: A true EMOM timer, streamlined for solo gym sessions or leading full group fitness classes.

FREQUENTLY ASKED QUESTIONS

What is an EMOM workout?
EMOM means "every minute on the minute." You start a new exercise at the top of each minute and rest for whatever time is left. Resero's EMOM timer handles the countdown and the cue, so you can focus on the work instead of the clock.

Can I use Resero as a HIIT timer or a Tabata timer?
Yes. Set any work-to-rest ratio you like, or load a ready-made Tabata protocol from the library. Resero works as a HIIT timer, a Tabata timer and a circuit timer without switching apps.

Does it work as a boxing timer?
Yes. Set your own round lengths, rest periods and warning bells for boxing, MMA, Muay Thai or kickboxing, with as many rounds as you need.

Can I time individual reps?
Yes. Sub-timers let you time each phase of a rep — negative, hold and positive — so a tempo prescription runs itself while you lift.

Does Resero work offline?
Yes. The entire workout timer runs without an internet connection, so a dead signal in the basement gym changes nothing.

WHO RESERO IS FOR

Athletes who need an EMOM timer that lasts a full session. Boxers and martial artists who want a dedicated round timer. Lifters chasing time under tension. Coaches who need a gym clock the whole class can read. And anyone tired of a workout timer that stops to show an ad.

Ditch the outdated gym timer. Download Resero today and give your workout the precision it deserves.
